ADJUSTABLE PUMP-HANGER.

Specification of Letters Patent.

Patented Aug. '7, 1917.

Application filed May 21, 1917. Serial No. 169,880.

To all whom it may concern: i

Be it known that I, JAMEs A. WooDs, a citizen of the United States, residing at Wichita, in the county of Sedgwick and State of Kansas, have invented a new and useful Improvement in Adjustable Pump- Hangers, of which the following is a specification, referring to the accompanying drawings. 7

The object of the invention is to provide an improved means for connecting and adjusting the length of the pump rods, which, operated by an overhead walking beam, work in conjunction with pump mechanism especially suited to the operation of pumping oil from deep wells.

In the drawings, Figure 1 is a side elevation showing the walking beam and the pump hanger in combination therewith and connecting to pump rods and pump within the oil well as illustrated in the sectional portions of the figure. Fig. 2 is a front view of the pump hanger. Fig. 3 is a side view of Fig. 2. Fig. 4: is a detail of the pin seen attached to the pump hanger in Fig. 2. Fig. 5 is an enlarged View of the end clamp and allied parts seen at the bottom of Fig. 3. Fig. 6 is an enlarged view of the end clamps and allied parts seen at the bottom of Fig. 2. Fig. 7 is a sectional view taken along the line AA Fig. 5 looking in the direction of the arrows.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

Referring to the drawings, in driving an oil well, a drive pipe 8 is first put down as the well is started, this pipe extends down for a considerable distance into the ground to case off water and other obstructions. Within this pipe 8, Fig. 1 is seen the casing 9 which extends to within a few feet of the bottom of the well. At- 10 is shown the stuffing boX and 11 is the stufiing boX housing and cap over the tubing 12. On the lower end of tubing 12 is located the working barrel or pump housing '13. At 14 is seen a perforated pipe through which the oil is sucked by the action of the pump. Pump rods 15 are located one above the other within the tubing 12 and are connected at their ends as at 16 by a union. The bottom rod 15 is connected to the pump in the bottom of the well. At 17 is seen the walln'ng beam adapted to rock on its support 18 as 24: of the pump hanger. Just below the riveted portions 26, the outer portions 28,

28 of the bar are separated and lie parallel to one another, each terminating in a block 29. Each block 29 is fashioned at 30 to properly receive the adjusting rod 15 and permit it to extend up between the parallel portions 28, 28 of the hanger. The blocks 29, 29 are reversed as seen in Fig. 6 and by means of bolts 31, the blocks are drawn together whereby the portions 30, 3O tightly clamp around and engage the rod15. A looped bar 21 is attached by the rivets 25 to the pump hanger 19.

In Fig. 1, the walking beam 17 is provided at 32 with a bearing adapted to receive and house the pin 23 which is permanently fastened to the bar 20 by means of the groove 22 and rivets 25. By means of a hook engaging the loop 21, the pump hanger 19 may therefore have its pin 23 lifted into or off the bearing 32. It will thus be seen that the operation of the walking beam will raise and lower the pin 23 and attached pump hanger 19 and allied rods clamped by 30, 30 of 19 whereby the pump will operate to pump the oil from the well as desired. Twisting the portions 24 at 27 is for the convenience of the workmen in adjusting the pump hanger 19 to the upper rod 15 and also for handling in the derrick.

The above described arrangement of parts permits of a very easy way of adjusting the length of the sucker rods which work the pump.

Such other modifications may be employed as lie within the scope of the appended claims.

Having fully described my invention what I now claim as new and desire to secure by Letters Patent is:

1. A pump hanger comprising a bar bent intermediate its ends around a pin and secured thereto, portions ofsaid bar lying in contact and being integrally connected for a distance outwardly from said pin, thence diverging to form parallel members, spaced apart, each of said members terminating at its outer end in a block, said blocks being arranged opposite each other and forming clamping means adapted to receive, house and clamp the upper portion of a pump rod in the manner as specified.

2. A pump hanger comprising a bar bent intermediate its ends around a steel pin and secured thereto, portions of said bar lying in contact and being integrally connected for a distance outwardly from said pin, thence diverging to form two parallel members, spaced apart, and terminating in end blocks lying adjacent to each other, and a twist formed in said contacting connected por tions of said bar; said end blocks being adapted to receive, house and clamp the upper portion of a pump rod in the manner and for the purposes as specified.

3. A pump hanger comprising a bar bent intermediate its ends around a steel pin and secured thereto, portions of said bar lying in contact and being integrally connected for a distance outwardly from said pin, thence diverging to form two parallel members, spaced apart, and terminating in end blocks lying adjacent to each other, and a twist formed in said contacting connected said pump rod; said pump hanger comprising a bar bent intermediate its ends around a steel pin and secured thereto, said pin being housed in the bearing in said walking beam; portions of said bar lying in contact and being integrally connected for a distance outwardly from said pin, thence diverging to form two parallel members, spaced apart, terminating in end blocks ar ranged opposite each other, said blocks being adapted to receive, house and clamp around the upper portion of said pump rod in the manner and for the purposes as specified.
